What is a pressure control valves?

1.check valve is only liquid flow along the inlet pipe, drain material but can not flow back, check valve is also known as check valve or check valve. Used in hydraulic transmission systems to avoid reverse flow of oil row, or used in pneumatic control valves to avoid the reverse flow of air compression.


2. Check valve has straight-through and right-angle two kinds. Straight-through check valve with a flange connection assembled in the pipe on the road. Right-angle check valve has a flange connection, flat coupling and live sleeve flange three ways.


3. The key to the function of the check valve or manipulate the oil only to move in one direction.


Differential pressure control valve should meet the following performance requirements.


(1) when the oil towards a direction through, frictional resistance to small, in other words, pressure damage to small.


(2) the valve core and valve block touching the airtightness is better, to completely no leakage, when the oil from the reverse back to flow, should be completely not according to.


(3) the operation of the check valve should be fast and dexterous, should not have collision and noise when working.


One-way valve in the hydraulic transmission system efficacy.


1 If the check valve is assembled in the pump inlet and outlet, can avoid the system software pressure suddenly increase and destroy the gasoline pump, that is, the start back to the effect.


2 If the check valve and self-operated differential pressure control valve or regulator parallel, can form the actuator positive direction slow speed, reverse rapid; or positive direction speed reduction, reverse random commodity circulation control circuit.


3 If the check valve and pressure valve in series down, can significantly improve the regulation pressure, to avoid the pressure of the reaction force.
